China's anti-graft chief He Guoqiang on Monday called on the discipline inspection agencies dispatched by the Central Commission for Discipline Inspection to make due contributions to the fight against corruption.

The agencies should strengthen the supervision over the leaders of relevant units, further investigate the cases of dereliction, bribery and abuse of power and focus on cases leading to mass incidents and other serious ones, He, head of the commission, said in a meeting in Beijing.

The CCDI agencies played an important role in China's great achievement in fighting against corruption in 2009, said He, a member of the Standing Committee of the Political Bureau of the CPC Central Committee.

Despite the achievements, the unified management of the CCDI agencies is a new thing that need to be improved in practice, he said, urging the agencies to explore new ways in curbing corruption.

He also called on the government organs to support the work of the agencies and help to solve the discipline inspectors' difficulties in life and work.
